[certbot] port upgrade fails

[Bjarne D Mathiesen]

1) upgrading these fails :
        certbot          0.37.1_0 < 0.37.2_0
        py37-acme        0.37.1_0 < 0.37.2_0
  I'm getting http 404 error on all repositories

2) they have been upgraded to 0.38.0
        https://github.com/certbot/certbot/
   but I'm also getting http 404 on all repositories for that

It seems as if all the necessry files are in
        https://github.com/certbot/certbot.git
but I don't know how to properly integrate a git in a portfile
